COMPOUND PAPER FLOOR-COVERING.

SPECIFICATION forming part of Letters Patent No. 228,194, dated June 1, 1880.

Application filed April 29, 1880.

To all whom it may concern Be it known that I, HENRY HAYWARD, of New York. in the county of New York and State of New York, have invented certain Improvements in Compound Paper Floor-Coverings, of which the following is a specification.

The object of my invention is to produce a cheap, and durable substitute for oil-cloth for covering floors; and to this end it consists in a sheet composed of paper and comminuted cork and a continuous strengthening-web of un woven fibers united with or incorporated into the sheet, which latter is finished with a surfacing of oil-paint or an equivalent coating.

In preparing myim proved article I take any ordinary paper-pulp of a cheap qualitysuch, for example, as Wood-pulp or straW-pulp-and combine therewith from fifteen to thirty per cent. of ground or finelycomminuted cork. The compound as above is reduced to a sheet form on an ordinary paper-machine, or by special apparatus, if preferred. If preferred, the cork may be added as the pulp is run out into a sheet but the best results are secured when the two are combined at the previous stage. I combine therewith a continuous strengthen in g-web composed of long fibers, such as jute,

hemp, or flax, crossed indiscriminately. This web may he laid on the under side or the up per side of the sheet, or introduced into the interior 5 but care is to be taken in every case that the fiber is united with and securely incorporated into the sheet. If preferred, two

webs may be used, one on each surface of the sheet. After the sheet with the webbing therein is completed and thoroughly dried it is coated thoroughly on both surfaces with oilpaint and printed or otherwise ornamented in the same manneras oil-cloth.

The paper gives to the sheet the required body and stiffness, While the cork gives elasticity, prevents cracking and breaking, and affords a very durable wearing-surface. The fiber gives tensile strength and ties the entire body together in all directions;

Having thus described my invention, what I claim is- 1. The floor-covering having its body composed of paper, comminuted cork, and a continuous web of unwoven fiber, united as described.

2. The floor-covering consistingof the paper sheet or body, the comminuted cork incorporated therein, one or more continuous webs of strong unwoven fiber, and a surfacing of oilpaint.

3. The herein-described method of manufacturing a floor-covering, consisting in combining paper-pulp and comminuted cork and reducing the same to a sheet form, and combining therewith during the latter operation a web of loose unwoven fibers.

HENRY HAYWARD.
